Abstract
Crown ether (S,R,R,S)-1 containing chiral subunits derived from (1R,2S )-cis-1,2,3,4-tetrahydronaphthalene-1,2-diol and the phenol moiety bea ring the intra-annular OH group and the 2,4-dinitrophenylazo group at its para-position have been prepared in enantiomerically pure form. Th e association constants for the complexes with chiral amines have been determined at various temperatures by the UV-visible spectroscopic me thod and thermodynamic parameters of complex formation have been calcu lated.
